Abstract

In this article, we present the design and characterization of the first 3D-printed guided-mode filter for terahertz frequencies. The device consist on a diffractive grating fabricated on top of a rectangular dielectric waveguide by 3D printing. Finite difference numerical modeling shows this device acts as a filter at a frequency that can be geometrically engineered and tuned around such frequency by varying the radiation incidence angle. Three devices were designed to operate at 200 GHz, 250 GHz, and 300 GHz; the devices were fabricated and successfully characterized using terahertz time-domain spectroscopy.
